A companion research effort looked at concepts for a new generation of supersonic transport aircraft capable of meeting NASA's noise, emissions and fuel efficiency goals for 2030.
一项合作研究成果着眼于新一代超音速运输飞行器的概念，以满足NASA为2030世代设定的噪音、排放和燃油效率目标。
Here it would reach supersonic speeds and then shift to its scramjet engine. The scramjet scoops up air and mixes it with fuel so it burns as the mixture flows through the engine at supersonic speeds.
这里它将达到超音速然后超高速冲压喷气发动机切换成工作状态，迎面气流进入发动机，与燃料混合，混合物在超音速状态流过引擎。
Then the influence on flame structure of supersonic combustion of ratio of length and deep of cavity, obliquity of back edge of cavity and different schemes of fuel injection were studied.
用这种方法研究了不同凹腔长深比、凹腔后缘倾角和不同燃料喷注方案对超声速燃烧火焰结构的影响。
